REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 391,620, dated October 23, 1888.

Application filed September 5, 1887.

To all whom it may concern.-

Be it known that I, HENRY P. JUDsoN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Refrigerators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a refrigerator having a close ice-tank, of metal, adapted to be filled from the top and placed between two refrigerating-chambers and air-conducting passages of a peculiar character, so that the air of each refrigerating-chamber is caused to circulate therein and is cooled by contact with the cool metal of the ice-tank, and one tank serves to cool the air of two chambers.

It further relates to various details of organization and construction, all of which will hereinafter be described.

In the drawings, Figure 1 is a view in perspective of a part of the refrigerator to show the interior construction and organization thereof. Fig. 2 is'a view in perspective of the exterior of the refrigerator. Fig. 3 is a vertical section thereof.

A represents the casing of the refrigerator. It is substantially rectangular in horizontal section, has the top composed'of the inclined sections a a and the intermediate flat section, a".

B is one refrigerating-chamber, and B the other.

I) is the door to the chamber B, and it is arranged in the section a of the top to swing upwardly on the hinges b.

b is the door to the chamber B, and it is arranged in the section a of the top to swing upwardly on the hinges If. The flat section a of the top has the door I)", through which ice is supplied to the tank.

The ice-tank O is made of metal, preferably galvanized iron or zinc, and it has the rounded bottom 0, which extends very nearly to the bottom of the refrigerator, and has the flanges c, by which it is suspended from the frame work of the top of the refrigerator about the opening b and it has no communication with either of the chambers B B. There is arranged Serial No. 248,785. (No model.)

on each side of the ice-tank O the partitions c 0 The partition 0" extends from a point substantially upon a line with the bottom of the icetank to a point about two or three inches (more or less) from the inner surface of the top, and forms a somewhat narrow passage, c, which is connected at its top and bottom with the refrigerating-chamber B. The upper edge of the partition 0 is beveled or inclined at 0 (See Fig. 1.) The partition 0 is of the same size and shape as the partition 0", and is arranged between the side of the icetank and the refrigerating-chamber B, and forms the passage 0', which is connected at its top and bottom with the refrigerating-chamber B. Below the bottom of the ice-tank Ois an inclined trough, D, which conveys the wa ter from the tank to an escape-trap, d. The water escapes from the tank through the escape-trap d. The trough and its support act as a part of a partition to separate the chambers B B, and to completely separate them I use a thin board or plate, d extending between the walls of the refrigerator and from the under surface of the ice-tank to the upper surface of the trough. (See Fig. 1.)

Each refrigerating-chamber B B may have the rows of removable cross-slats E extending from side to side any desired distance from the bottom of the chamber, in order that the bottom of each chamber may be utilized for the storage of articles which are not required to he often removed from the refrigerator, and the refrigerator may also be provided with any desired number of shelves extending from the sides of the chamber, and made of slats, in order to interrupt the circulation of air in the chambers as little as possible, and also to permit the air to reach all sides of the articles placed on the shelves.

It will be seen that by this construction a refrigerator is provided that has two refrigerating-chambers, B B, which are disconnected, and which, while being disconnected with each other, are cooled by the same ice by the location of the ice-tank between the two chambers in such a manner that one of its surfaces acts as a portion of a wall of one of its chambers, while another of its surfaces acts as a portion of the wall of another chamber; also, that the refrigerator is so shaped that the air is caused to circulate therein in the direction indicated by the arrowsthat is, the air in contact with the cooled metal side of the refrigerating-chambers descends through the refrigeratingchamher, and by the inclined surface f is caused to be moved toward and into the upper part of the passage.

By making the entrance to the refrigerating chambers as described there is but compara tively little escape of cooled air upon the opening of the doors, and by making the ice-tank close there is no loss of the cooling power from it at any time except when it is uncovered for the purpose of replenishing it with ice.

For household purposes it is generally advisable to use the refrigerator with the two chambers 13 B separated from each other by the partition D d", as shown in Fig. 1. For commercial uses, where articles of the same kind only are to be refrigerated, the section (1 of the partition or the entire partition may be removed, thus connecting the chambers B B below the ice-tank.

I am aware that it is not new to provide re- Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a refrigerator, the combination, with 40 the closed ice-tank 0, arranged in the center of the refrigerator, and a partition below the said tank to serve with the latter to divide the interior of the refrigerator into two refrigerating-chambers, both of which will be cooled from the said ice-tank, of the partitions c 0 adjacent to but separated from the sides of the said tank to form the airspaces a c, and the inclined upper walls at the tops of the said refrigerating-chambers, substantially as set forth.

2. In a refrigerator, the combination, with the closed ice-tank 0, arranged in the center of the refrigerator and having a door or cover to permit of access to said tank from the outside of'the refrigerator, and a water-escape pipe, (1', of the partition d below said tank, the trough D below said partition and escapepipe, the partitions c" 0 adjacent to the sides of said tank, butseparated therefrom and having air-spaces above and below them in the two chambers of the refrigerator, and the inclined upper walls at the tops of said chambers, said inclined walls being formed partly by the doors b b ,WhlC11,Wh6l1 opened,permit of access to the said refrigerating-chambers, substan- 65 tiall y as set forth.
